Production process for easy decontamination shrink-proof bleaching liner

Abstract

The invention discloses a production process for easy decontamination shrink-proof bleaching liner, comprising the steps as follows: instantly rolling alkaki, extinguishing fire and cooling after singeing the base cloth, NaOh in the alkali liquor being 10-15 g / l, the refining agent being 6 g / L, keeping the thermal and moisture and stacking for 10 to 12 hours, then open washing and desizing under 95 degrees centigrade; whitening; the sodium hypochlorite solution is added with refining enzyme and oxyful, the bath ratio being 1:8 to 1:10, the bleaching time being 30 to 45 min; and whitening, shrink proofing and soil-releasing finishing; utilizing polyamide hot-melt adhesive to carry out double-point coating, the cylinder being 40 screen meshes, the aperture being 0.29 mm, the thickness being 0.18 mm, and the vehicle speed being 40m / min, the drying room temperature being 170 to 180 degrees centigrade, the environmental temperature in shop being 20 to 30 degrees centigrade, the humidity being 60% to 70%; finally utilizing non-contact hot wind to pre-dry such that the lapping cloth has the special functions of shrink proofing and soil-releasing finishing the same with the material, and has water repellent and oil repellent functions.

Description

technical field [0001] The invention relates to a production process of an adhesive lining, in particular to a production process of an easy-to-decontaminate and shrink-proof bleached lining. Background technique [0002] After the product is bonded to the fabric with waterproof, oil-proof and easy-to-decontamination requirements, since the adhesive interlining has not undergone any treatment, it cannot achieve easy decontamination and certain water-repellent and oil-repellent functions, which affects the overall shape of the fabric. . [0003] In the bleaching process, the traditional pretreatment process is to use about 40g / L NaOH to deboil, then boil in a bleaching or boiling cloth pot, and then bleach with chlorine and hydrogen peroxide. In this way, not only the process is long, the alkali consumption is high, the fabric damage is large, but also the discharged sewage has high alkalinity and high COD value. During sewage treatment, a large amount of acid is required fo...

Problems solved by technology

[0005] The purpose of the present invention is to provide an easy-to-decontamination and anti-shrinkage bleached interlining production process, which can effectively solve the problem that the existing adhesive interlining cannot be easily decontaminated and has certain water-repellent and oil-repellent functions. The pre-bleaching process needs to consume a large amount of alkali on the fabric. The damage is large and not conducive to environmental protection. The three processes of whitening, anti-shrinkage, and easy decontamination finishing need to be carried out separately
